tracks and 11Vare a series ofwork cars or V- tables 12 supported upon wheels 13 rolling alon i said tracks. The tables 12 are preferably coupled. together to form acontinuous train during their travel along working t-rack 10 and are adapted to carry glass sheets secured to the tops thereof to the left in the direction indicated by the arrow in Fig. 1,k

beneath the grinding and polishing machines referred to above. When the tables 12 reach the left handend of working track 10the glass sheets are rem/oved therefromafter which said tables are Vtransferred to the' return track 11 and carried therealong in the opposite directionV to the' starting end of Working track 10.

. The means herein providedv for transferring thecars or tables 12 from the working track 10 to return track 11 at one end of the system and from the return'tr'ack 11 to Work',-

v ingtrack 10 at the opposite end fof the system preferably includes a rotatable transfer,l

or turntablelll, said table carrying the four individual track sectionsl, 16, I17 and 18,' the track'sections 15 yand 17 being parallel with .one another while thetracksections 16 and 18 are also parallel with oneanother andvpositioned at substantially right angles to"k the firstv mentionedtrack sections 15 and 17.

Upon rotation of the turn table 14, the indi- Positioned outwardly lofthe turn table 14' at one side thereof is an auxiliary track `22 in alignment with the Working track 10 and also with that particular. individual track section on the turn table which happens to be in registry with the'workingY track.l The auxiliary track 22 is providedprimarily to carry an operating car or dinkey 23 which comprises, asillustrated in Figs. 2 andc3, a truck 24 supported upon` Wheels 25, said dinkey v,being operated from a motor 26 supported upon the truck. .The shaftv 27 of motor 26 is Ysuitably connected withashaft 28 carrying a'worm 29 meshing Witha worm gear 30 secured to horizontal shaft 31 journaled in the opposite side walls ofcasing 32.

` Mounted in alignment with shaft'31 is a shaft 33-connected thereto by means. of a suitable Vcoupli-ngw34, said shaft 33 being ournaled in the opposite 4side walls of a casing 35 and carrying Within Vsaid casing la spur gear 36 meshing With a drive pinion 37 keyedto one of the axles`38 of theV dinkey and Which axle carries supporting wheels 25. Thus, 'upon opera-tion ofthe motor 26, the axle 38 will vbe positively `driventhrough the mechanism above described to'V effect the desired movementof the dinkey. Y Y

It is, of course, desirable'upon stopping of the motor 26 that the dinkey be brought to a relatively quick stop and to accomplish this, f

there may be provided a magnetic brake of the type illustrated in Fig. 4 and designated in its entirety bythe numeral 39. The brake 39 comprises a brake ,Wheel' or drum 40 mounted upon Vand secured to the axle 38 by means of ay key 41. The brake 39 further includes a horizontal base member42 secured to the bottom of the dinkey truck 24 and having pivoted thereto at one end, as indicated at 43, a depending shoe lever 44 carrying a shoe45 adapted to engage brake Wheel 40. Carried adjacent the opposite end of base member 42 is a depending 4field member 46 also pivoted to said base member. asV at 47, and carrying. a

vcoil or magnet 48. Also'pivoted to the base member 42 is a shoe lever 49 carrying the shoe 50 adapted to engage brakewheel v40 opposite brake shoe 45. Carried at the lower endof shoe lever 49 'is an armature lever 51 positionedopposite the coil or magnet 4 8 and'V having connected thereto Yone endnof a compression spring 52-which passes throughrthe field-member 46 and bears at its outer end c against a lspring gland Connecting the lower ends'of the shoelever 44 and Vfield member 46 is alpull rod 54, pivoted to the latter as at 55, the opposite end of said rod being threaded andr extending through a bearing 56 pivoted as at 57 to shoe lever44..V The pull rod 5,4is held inpropery position by two nuts 58 and 59V threaded thereupon at yopposite' ends of bearing'56.y Y A' Y The magnetic brake-39 is ries with the motor 26 .on dinkey 23 and rwhen the power is on and said motor isoperating, the brake is released andwhen thepower is shut olf to stopzthe motor the brakeisset.

. c Y. 10oconnectedY in :se-` c For instance, when it is 'desired to move the i dinkey 23 forwardly, the motor 2,6,thereofis placed in Operation and simultaneously the coil or magnet 48 willbe energized.V The energization of this coil acting in conjunction with compression spring 52 will tend to move rocked outwardly about'its pivot 47 to movei Y' i V shoe 50 out of engagement with wheel 40. Onthe other hand, when the motor 26 is stopped,the coil ormagnet 48 willbede-energized and the compression spring52 will then act to force the Ashoe lever 49y inwardlyv and the lield member 46 outwardly which .will draw-the shoe lever 44 ini'vardlyinto engagement with the Vbrake, Wheel or vdrum l40 and thus bring the dinkey to :a stop. e.

vAccording to the present invention, th operating car or dinkey 23 is adapted, as will Y be later more fully explained, to travel to the 'the field member 46 and shoe lever 49 simul- Y iso y right from v4auxiliary track 22 across the table '14 4and engage the irst or endworkl table12on `working track 10, after which the vtravel of the .dinkey isreversedtofpull the `and this latter operationnmayfbe accomplished by the provision of an overhea'd"push er designated in its entirety bythenuinber 60, and comprising preferably an endless hori Zontal chain driven from amotor 61-'throug-h the intermedia-ry' of suitable reduction gearing and Vcarrying one or a plurality Vof pusher elements (not shown) whichengage the rear endof the work table and push the same from the turn table onto the return track. w

Asl brought out gabove, the transfer of the work cars or tables lfrom 4working track `10 toV return track A11-is adapted to be'reffected automatically and without any manualwaid or assistance. To this end, there: are positionedbetween the rails ofthe working'track 10 adjacent the turn Vtable 14, the three switches "62, 631and 64, saidl switchesgbeing positioned in longitudinal alignment f with one another, with the switches 62 and 63 rel;

atively close together. Also positioned betweenthe rails of the auxiliary' track 22Lare two similar switches 65 and 66, said switches being inlongitudinal alignment with `the previously mentioned switches 62, 63 and.

64., There is further positioned outwardly of but adjacent to the working track 10, a switch 67. The several switches referred to above are preferably of the same construction and each is adaptedto be controlled, as shown in Figs.v 5fand 7,by the4 provision of a starwheelor the llike l68 havinga plural.- ity'of radiating actuating fingers 69. vThe switches 62, 64,66 `andf67 are connected in series withthe motor 26 andfmagneticbrake 39 carried by dinkey 23 `'while the switch 63 is connected in series with the motor 61V47 for the overhead pusher 60 andthe switch V65, motor 191foris vconnected in `seriesQwith the turntable 14. i j i In operation and upon'moyem'ent ofthe work tables 12 to the left along working track 10, the depending plate 701.(Fig. 7j

Vcarried atthe forward end of the work table, will engagethe vstar-wheel 68 `of switch 62 and rotate said wheel in a manner ,to close said switch. Y This willfcomplete an 'clectrii- Vcal circuit'through the, ldinkey inotor26 and magnetic brake` 39 fto start the `di'nkeyfoit wardly to the right'across the turn table 1 4 and such forward Qmovement` of `the dinkey will continue untilthe switch plate'l (Fig. 5) carried upon the outerfside ofthe vdinkey Vand pivoted theretov as ,at 72fengages kthe rdinkey toa stop.
